I never really have the syptoms that you are talking about but I have gotten the odd rash when working for too long or too near my anemones.  Perhaps you're having some type of allergic reaction. 
 
Ditto on the gloves, they have helped a lot, plus no fears of colognes, etc getting into the tank. 
 
Hope you feel better!
